HeidelbergCement hosts the LEILAC Demonstration plant

HeidelbergCement has nominated the Hannover site to locate the LEILAC2 Demonstration carbon capture plant after an extensive suitability assessment of several operational sites in Germany.

The European Commission carried out its own assessment and has validated the proposal, with the project receiving € 16 M of funding under H2020. Capable of separating 100 ktpa of CO2 per annum, the Demonstration plant is a critical step in demonstrating the application of this novel carbon capture process to the cement and lime industries.

HeidelbergCement's Chairman of the Managing Board Dr. Dominik von Achten said:

"The LEILAC technology has the potential to enable the cement and lime industries to efficiently capture their process emissions on an industrial scale,"

"The project in Hanover is one of several promising CO2 capture technologies that we are currently testing at full speed within the HeidelbergCement Group."

LEILAC 1 pilot

The LEILAC2 project aims to address the major remaining hurdles before commercial, global rollout. The module will be capable of capturing 20% of the plant’s capacity, or around 100,000 tonnes per year.

The technology is low-cost, scalable, replicable and retrofittable. Starting with the fully operational Hannover plant, the project looks to show how the design can be retrofitted to all existing cement plants without dramatically increasing their costs. Fully developed, supported, and accepted use and storage infrastructure will be required to ensure the CO2 is not ultimately released into the atmosphere.

Phil Hodgson, MD of Calix and Chairman of the LEILAC-2 Executive Board, said:

“We welcome HeidelbergCement’s commitment to their Hannover site for the integration of the LEILAC-2 demonstration unit. This commitment is an important milestone in the project, and we look forward to working with HeidelbergCement and our other LEILAC-2 partners to make the project a success, and demonstrate at meaningful scale the ability of the technology to help the cement industry mitigate CO2 emissions”.

Jan Theulen, Director Alternative Resources, HeidelbergCement said:

“The LEILAC1 project has successfully demonstrated that both limestone and raw meal can be processed, that the unavoidable process CO2 is successfully separated, and that the technology fundamentally works. With the tireless efforts by the project team – with multiple organisations contributing their time and expertise from across the globe – we are confident that this scale-up step can be achieved.”

By providing a low-cost means of capturing hard-to-abate CO2 emissions, the LEILAC process has the potential to allow the cement and lime industries to efficiently capture their process emissions while continuing to safely and efficiently operate. Our aim is to enable industry to serve society and efficiently meet market demand, while achieving the Paris Agreement’s ambitions.

The LEILAC2 Project is currently undergoing its initial engineering phase, developing a Basis-of-Design, which is targeted for completion by end June 2021. Following further engineering, it is anticipated that the Demonstration plant will be completed by the end of 2023. The project will also include preliminary investigations into the use and or storage of the captured CO2.
